In situ fabrication of a solar nanofluid by a femtosecond laser ablation of tin in ethylene glycol

Harvesting solar radiation should be improved to make this type of renewable energy more competitive in economic terms. Furthermore, to develop “green” nanotechnology is a prerequisite for crossing the boundary between research and industrial applications. In this contribution we will show the synthesis of a solar nanofluid of tin with ethylene glycol by pulsed laser ablation in liquids, a green and sustainable method for nanoparticles production. We will demonstrate that the nanofluid obtained with this technology is more stable that the one synthesized by conventional chemistry and have a reduced solar irradiance transmission through the time.
